Key Benefits
- Delivers 261 kW (345 HP) at 1500rmp from 14L as a factory-rated assembly.
- Turbocharged induction with water cooling keeps charge temperature under control in continuous duty.
- Published fuel consumption of 207 g/kW.h makes running cost predictable.
- Supplied as a complete engine assembly, so the unit goes straight onto the mounts
- Backed by a written warranty of one year or 1000 hours, whichever comes first
Application Scenarios
- Prime mover for a new generator set build
- Standby set engine replacement
- Rental power fleet rebuild
- Containerised power module
Who It Is For
- Genset packagers matching an engine to an alternator
- Rental power companies rebuilding sets between contracts
- Industrial sites replacing the prime mover in an existing canopy
- Telecom and data infrastructure contractors specifying standby power
Problems It Solves
- An engine that does not hold speed under block load makes the whole set unusable.
- Packagers lose weeks when the engine does not match the alternator and the base frame.
- Standby sets sit idle for months and must still start and take load on demand.
- Identifying the right NTA855-G1A variant from a serial number takes experience; MEP Power checks the configuration before quoting.

How It Compares
| Compared with | What to consider |
|---|---|
| A rebuilt or used engine of the same rating | A rebuilt unit may show the same 261 kW (345 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same NTA855 range | Moving up a frame size adds weight, envelope and fuel burn; specify the next size up only if the duty cycle really needs the headroom. |
| A non-Cummins engine of similar output | Parts and service for Cummins families are available in most markets, which matters more over ten years than the purchase price on day one. |
